ffmpeg 'unknown entry' error
I am encoding a video clip, with ffmpeg, using x264 encoder. At the same time, I am overlaying a subtitle stream onto the video (burning in my subs).
My command line is ; Code:
./ffmpeg -i /video.mkv -i /Subtitles_exp.idx -filter_complex '[0:v][1:s]overlay[vid]' -map '[vid]' -s hd720 -sws_flags lanczos -c:v libx264 -crf 20 -preset medium ~/Desktop/test.mkv The problem is that during encoding, ffmpeg regularly outputs the following message ; Code:
[matroska,webm @ 0x1b40000] Unknown entry 0x1654AE6B0:11.26 bitrate= 264.0kbits/s Does anyone know what this means ? Thanks. |

It means that ffmpeg is coming across chunks in the file that it has no idea what to do with. If the latest build has the same messages, you might want to open a ticket with ffmpeg and upload the file to their ftp server (upload.ffmpeg.org). Try a nightly build first.
The unknown packets being skipped shouldn't be a problem, most of them are just extra information, but if it's important it could mess up your whole video. |
